After running for several minutes all havoc breaks loose. My alternator isn't quite doing its job. The engine runs rough and is flooding. I've replaced battery, sparkplugs/wires, alternator, distributor cap, fuel pump, and fuel filter. The only thing that helped for 3 days was the fuel filter and sparkplug changes. My air compressor is giving out,,could this be my problem?


The fuel regulator in the TBI may need to be rebuilt. Can check with a fuel pressure gauge. Also the injectors may need to be replaced.
